Hi devs:

Just now Dan and I found a bug for cache file name. Currently after 
download a doc, the cache manager will assign it a name. The name come 
from download time (by milli seconds) with file extension ".dat". It 
worked fine for a while.

But dan got a fast machine, then issues came out: it seems when he tried 
to open a workflow (there are 10 data resource actors there), two 
documents can be download at exactly same time and manager assigned same 
cache file name to them. One will overwrite another one. Two different 
data source will point to same chache file.

I think we should need another mechanism to assign cache file name.
